Solving equations using graphs

Algebra

Find the roots or solve f(x)=0 as an alternative way of asking for a solution to the trinomial equal to zero. Solve trinomials of type e.g. x²+2x+2 = 4 after having drawny = x²+2x+2 or y = x2+2x+1 or y = x²+x-3 by drawing a linear graph or reading off points. Also solve cubics, reciprocals and exponentials equations with the aid of graphsPlay Now
